Almost always, there would be an inline fuse after the power cord connector line to the circuit board inside the TV. With a completely dead TV unit, this would be the preliminary suspect, it would have blown.

How the fuse is blown would be significant. If it is a clean break, then chances are that it has blown due to a power surge and replacement should fix the problem.

If however, the blown fuse exhibits black powdery burnt markings, then it would indicate that another component has faulted causing excessive current resulting to the fuse blowing.

Options then are:

consider a DIY (do-it-yourself) repair if and only if comfortable working with electronic components & circuitry, use of a DVM/VOM, a soldering iron/station and safe practices with electrically powered devices. Access to a Service Manual or at the very least, a schematic diagram would be a necessity;

should you be uncomfortable with a DIY, perhaps your best bet would then be to consult with and/or seek the services of an authorized Service Center or a qualified professional.

tried replacing the fuse as suggested (it was blown) but the new one popped immediately, leaving a black residue inside the glass. There are no service agents down here, and very few technicians - any idea what i could try next? would you have access to a wiring diagram or service manual for this unit (serial # XXXXX model Sankey CLCD-4220BL)
